Inventor: KUWAJIMA SOICHI
IPC: B01D29/09

Abstract: Apparatus has a rotary drum (1) provided with a heating jacket (12) therearound. The drum is mounted on a base (3) pivotally supported on a pedestal (2). The base (3) can be caused to take different orientations so as to enable the drum to take different attitudes. While the drum is in a vertical position, a mixture of fine particles and a liquid is supplied into the drum through a supply passage (27) formed axially in a rotary shaft (24) which extends into the drum rotatably and axially slidably relative to the drum. The mixture is filtered through a filter (21) disposed in the drum. Filter liquid is discharged to the outside. The particles are prevented from passing through the filter and remain in the drum. Thereafter, the particles are heated and dried by a heating jacket (12) on the drum while the drum is caused to assume a horizontal position and being rotated. The drum is then inclined such that the initially upwardly directed end thereof is directed obliquely downward. Thereafter, an agitating blade (25) and sweeping blades (26) on the inner end of the rotary shaft (24) is rotated and shifted axially, whereby the dried particles are agitated and swept, to be discharged to the outside.

Abstract: A feeder mechanism (10) for feeding load items (12) in a predetermined spaced relationship into a loading station of a carton loading machine comprises at least two conveyors which move at different speeds along the same path and elevator ramps on each of the conveyors. The primary conveyor (60) has a forward run mounted for movement at a first predetermined speed in a forward direction. The forward run (70) hasg an input end (76) for receiving load items (12) and it extends forwardly from the input end into a spacing station (104). The secondary conveyor (62) has a forward run mounted for movement at a second speed in the forward direction which is faster than the first speed. At least a portion of the forward run of the second conveyor is located adjacent and coextensive with a portion of the forward run of the primary conveyor (60) in the spacing station (104). A plurality of elevator ramps (122) are mounted on the secondary conveyor (62) at longitudinally spaced intervals therealong. Each ramp (124) has a ramp face (126) which is upwardly and rearwardly inclined in a direction opposite to the forward direction. The leading end (136) of each ramp (126) is disposed at or below the level of the adjacent primary conveyor and the trailing end (130) of each ramp being disposed at a level above the level of the adjacent first conveyor. The ramps are aligned with load items supported on the first conveyor in use such that as the secondary conveyor accelerates the ramps with respect to the primary conveyor, the ramp face will pass under a load item and elevate it out of contact with the primary conveyor and thereafter transport the load items through the spacing station with successive load items being spaced from one another.

Abstract: Ein Stufengetriebe für Kraftfahrzeuge weist ein erstes Zahnrad

meinsamen Welle nebeneinander angeordnet sind. Zwischen den 
Zahnrädern (12) und relativ zu diesen axial verschiebbar 
sind Synchronisierungsmittel zum Angleichen der Drehzahlen 
der Zahnräder (12) vorgesehen. Ein Betätigungselement der 
Synchronisierungsmittel läuft mit dem ersten Zahnrad (12) um.

Um synchronisierte Schaltvorgänge mit konstanter 
Schaltzeit ausführen zu können, die unabhängig von der manuell

Keilfläche (51, 51′) auf, die an einer zugeordneten zweiten, 
mit dem ersten Zahnrad (12) drehstarr verbundenen Keilfläche 
(41, 41′) anliegt. Dies geschieht derart, daß das Betätigungs­

     Abstract 
     A multi-step reduction gear for motor 
vehicles has a first gear (12) and a second 
gear mounted side by side on a common shaft. 
Synchronization means for adjusting the 
speeds of the gears (12) are provided between 
the gears (12) and slide axially with respect 
thereto. An actuating element of the synchronization 
means rotates with the first gear 
(12). Said element can be turned with respect to 
the latter only through a limited peri­
pheral section (u) andhas a peripheral friction 
surface which can be brought by axial 
sliding into frictional engagement with a counter-­
friction surface of the second gear. To 
permit synchronized shifting processes with 
constant shift time which are independent of 
the manually applied shifting effort, the 
actuating element has a first wedge face (51, 51′) 
set at an angle to a radial plane, which rests 
against a corresponding second wedge face 
(41, 41′) rigidly connected to the first gear (12). 
In this way, when frictional engagement 
occurs, the actuating element is subjected to an 
axial force which is directed toward the 
counter-friction surface (31).
